The dark blue lid has an emblem that resembles the Motor City's beloved Tigers and also lists the years that Eminem's solo albums were released, including 2013.
Entertainment Weekly said Tuesday the 2013 likely means his new project, which has been in the works since May, will drop sometime in the coming year. Not many details about the record have surfaced; however, producers Dr. Dre and No I.D. have reportedly been involved.
Eminem's last solo CD was "Recovery," which came out in 2010.
